TRAP FOR REFRIGERATORS.

Specification ofLetters Patent.

Patented Aug. 6, 191".

.application led October 5, 1911. Serial No. 652,935.

Be it known that,I, JACOB PoDoLsnY, a citizen ofthe United States, residing at Boston, county of Suiolk, and State of Massa chusetts, have invented an Improvement in Traps r:tor Refrigerators, of which the followmg description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to traps and particularly totrapslthat are adapted to Vbe used wlth refrigerators, ice chests, etc.

a simple and inexpensive trap for this purpose which is sustained ent-irely by the Waste pipe instead of by the f loor and which ca be readily put in place after the oor is laid and which has such a construction' that the cap can be readilyl removed for cleaning the trap without disturbing any of the other operative parts.

Further objects of the invention areto improve generally traps of this nature, all as will be more fully hereinafter described yand. then pointed out in the appended claims. 4

In the drawings I have shown in vertical section a trap embodying my invention.

8 designates the bottom of a refrigerator or ice chest and 4 a drip pipe extending therefrom through which the Waste water is delivered.

5 is the floor of the building on which the ice chest is supported, and 6 is'the waste pipe which is permanently placed in the house and which may lead to a sewer drain or any other locality. AIn a building or hou'se it is customar to place the waste pipes, soil pi es, etc., 1n the walls before the house is finis ed and after the house is linished to make the proper connections to them. i

As stated above my improved trap issuch that the trap connections to the waste i `6 can be readily made after the oor is a1d.

My improved trap comprises a pan-supporting member 7 1n the form of ashort piece of pipe which has screw-threaded connection with the waste pipe 6,'as shown at 8, and which is rovided at its upper end with a liange 9' orming a rest or support for the pan 10. The pan 10 may be cast iron or maybe made of sheet metal as desiredV and may have any suitable shape. This pan is designed to set into an opening specia 11 formed inthe iioor 5 and the-top ofihe.

pan will preferably Jproject slight-ly above thelioor, as shown in the drawings. The

pan rests on Athe iange 9 and is clamped in positionthereon by means of a clampingV member 12. This clamping member 12 is tubular and is provided with a nipple 13 which screws into the pan-supportingmem-y her '7 and is also provided with a clam ing flange 114 which clamps .the bottom o the pan against the flange 9. The pan is provided with an opening 15 in its 'bottom through which the nipple 13 extends and by The object of the invention is to provide the construction shown a suliciently tight joint can be made to prevent any leakage of water through the Vopening 15 in .the pan. This clamping member is also provided With the portion 16 which.extends above the liange 14 and over which the Water from the pan flows in passing to the waste pipe.

The seal for the trap is formed by a cap 17 which incloses the portion 16 of the clamping member and which is provided with apertures 18 iniits side walls. This cap is held in position by screw-threadin it to the flange 14, as shown at 19, sai

flange being exteriorly screw-threaded for this purpose.

In installing the trap the drain pipe 6 is built into the house as usual andvtie members 7 and 12 may be left in position. After the Hoor has been laid a hole is cut therein at the proper point and of the proper size t'o receive the pan 11, and the clamping member 12 is removed and the pan is then set onto the liange 9 and clamped in place by the clamping member 12. The cap 17 may then be applied and the trap is ready for use.

To clean the trap involves merely the removal'of the cap 17 and this can be readily accomplished without the aid of tools or appliances. Y Y

My improved tra is4 sustained entirely by the drain pipe an rejects v'er'y little, if at all, above the Hoor ine 5`.

While I have illustrated one embodiment of my invention I do not Wish to be limited to the constructional features shown.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is :1-5

1. In a trap foryefrigerators, the combination 'with a waste pipe, of a pipe section connected thereto" and having a flange at its upper end and being interiorly screW-' threaded at said end, a pan resting on said ange andl having an aperture registering with the pipe section, a clamping member having a nipple extending through the hole in the pan and screwed into the upper end of the pipe section, said clamping member having a fiange to overlie the bottom of the pail and clamp the latter against the flange of the pipe section, said clamping member being removable from the pipe section withl out removing the latter from the Waste pipe and having a .portion 16 extending above the iange, and an apertured cap covering on said ange and having an aperture registering with theopening of said member, a clamping member having a nipple extending through the hole in the pan and screwed into the supporting member and having a flange to overlie the bottom of the pan and clamp the lat-ter against said member, said clamping .member having a portion 16 eX tending above the ange, and a cap serewed to the ange of the clamping member and provided with apertures.

In testimony whereof, I have signed my name to this specification, in the lpresence of two smbseribing Witnesses.
